【 摘 要 】

In this paper, the high-density denitrifying bacteria on the immobilized carrier after acclimation were used to carry out batch experiments under different carbon source types, carbon-nitrogen ratios, temperature and pH conditions, and the process was investigated for low-concentration micro-polluted water sources. The treatment effect, as well as the kinetic characteristics of nitrogen removal and the nitrogen conversion pathway.
